<p>This issues seems to be related to <a href="https://github.com/rust-lang/rust/issues/69121">#69121</a> (reported on June). Is there something actionable for a discussion? Should someone from the <code>@*WG-mir-opt*</code> have a look at this?<br>
As there seems nothing to be on fire (albeit a regression...) could a <code>P-medium</code> be a good candidate for this issue?</p>

<p>Is this actually a MIR-opt issue? What caused it?</p>

<p>Can't exactly say why, by my limited knowledge I can only say that the compiler bumped in some code it could not generated. Yes, maybe a bisection like you added could help.</p>

<p>Does it need a ping to the cleanup group for that?</p>

<p>based on the same idea, non working code generating an ICE I'd go with <code>P-medium</code></p>
